Novel high-speed light-gas gun muzzle bullet-separating vibration damping system

Abstract

The invention discloses a novel high-speed light-gas gun muzzle bullet-separating vibration damping system. The system comprises a bullet-separating device cavity connected with a high-speed light-gas gun barrel via threads, and a viscoelastic high-damping rubber gasket and an elastic supporting baffle connected with the bullet-separating device cavity in sequence via a plurality of positioning shafts, each positioning shaft is sleeved by a spiral spring group, the spiral spring group of each positioning shaft is segmented into two parts via a spiral spring separating plate sleeving the positioning shafts, and end parts of the positioning shafts, far away from the bullet-separating device cavity, are connected with double-cylinder bullet-separating vibration dampers via threads. The high-speed light-gas gun muzzle bullet-separating vibration damping system is advantageous in that the occupied space is small, the mass is small, the system is detachable and portable, a bullet holder can be recycled, and the buffer effect is good; the bullet-separating vibration damping system and the barrel and the double-cylinder bullet-separating vibration dampers and the positioning shafts are both connected via the threads so that the dismounting is facilitated; the impact effect on a bullet-separating device by the bullet holder is alleviated via vibration damping spiral springs; and rapid attenuation of the vibration of the bullet holder is realized via the viscoelastic high-damping rubber gasket and the double-cylinder vibration dampers.

Description

technical field [0001] The invention relates to the technical field of light gas gun systems, in particular to a novel high-speed light gas gun muzzle ejection damping system. Background technique [0002] The light gas cannon system can make the projectile produce a speed as high as 50-8000m / s. The light gas cannon is a kind of experimental result with good repeatability, good parallelism and flatness in the impact process, and has the advantages of simple operation and convenient detection. system. Widely used in dynamic loading experiments. The light gas cannon system consists of a breech high pressure chamber, barrel and recovery chamber. During the experiment, after placing the experimental specimen in the recovery chamber in front of the barrel, the breech high-pressure chamber is filled with high-pressure gas, and the projectile fixed on the bullet holder is placed in the barrel, and the high-pressure gas is released to drive the bullet holder and the projectile tog...

AI Technical Summary

Problems solved by technology

In the test, the main research is the dynamic mechanical behavior of the projectile on the test piece, but for the general light gas gun, driven by the high-pressure gas, the projectile rest and the projectile are launched from the barrel together, causing secondary damage to the test piece. impact, resulting in a large experimental error
